Title: Improvements in Machines for Bottling Mineral Waters and other Liquids.
Inventor: HOWARD ELIOT
Filed: 1903-04-07
Granted: 1904-04-07
Abstract: 8077. Howard, E., and Dowell, H. J. . April 7. Bottling; corking.-Relates to bottling-machines of the class described in Specification No. 4908, A.D. 1882, whereby the bottle is prevented from descending when the cork is being driven in. The corks are made to protrude the same distance, whatever the height of the bottle, detachable guides being provided on the frame, and means being adopted for preventing waste of liquid if the bottle is broken. Fig. 1 shows the corking-mechanism. A cam a mounted on the spindle c engages a lever f, which is pivoted to the casing n at g and allows the spindle d of the bottle block x to be pushed up by a spring t a greater or less distance, according to the length of bottle. The spindle is jammed in the guide r, during the descent of the plunger, by a wedge i, allowed to fall by another cam b and lever l. In the arrangement shown in Fig. 3, the spindle d is lifted by the sliding piece u, to which it is attached. The slide u is actuated by a cam v on the spindle c, and has a rod 1 carrying a head 2, which engages a lever z, thereby causing the wedge y to rise or fall, jamming the wedge end of the spindle as before. In a modification, the wedge is operated. by a rod connected to the plunger that drives the cork. Fig. 6 is a section through the guides or slide facings, consisting of detachable parts 7, 8, for sustaining sliding friction between the slide 4, Fig. 1, and the frame n, and which are bolted to the frame, instead of the slides being constituted by a slot in the frame itself. Similar slide facings are used in connection with the slide u, Fig. 3, of the bottle-block spindle. Fig. 11 represents a device for preventing loss of fluid, and consists of an extra inlet valve 13 working on a seating in the mouthpiece 14. A strong spring 21, normally, acts on a double-armed lever 19 to keep the valve open, but, if a bottle breaks or is not put on to the bottle block, the latter rises, a projection on it moving a lever and pulling down a rod 17, which actuates the lever 19, thereby assisting the weaker spring 22 to close the valve. Fig. 12 shows a modification, with the ordinary inlet valve 24 in which the lower flange or tappet ring 25 carries a cam 26 rotating with the shaft c and free to move vertically on guiding-feathers 27 on the shaft. A rod 31 may be depressed by a lever actuated by a lug on the bottle block x, in case of accident, thereby allowing the tappet ring 25 to drop away from the bowl 33 of the valve 24, allowing the latter to remain closed by its own spring.

Granted: 1903-06-25
Abstract: 9651. Coombs, L. April 29. Couplings, non-automatic.-Relates to couplings for trams used in collieries. In order to prevent the coupling-pin C, Fig. 1, from jumping out of the shackle B, it is formed with lugs D, Fig. 2, at the bottom, which pass through slots E, Fig. 1, in the lower arm of the shackle and are then turned round to engage the underside of the shackle. In order to prevent the pin C from turning back accidentally into a position in which it could jolt out, a catch G, consisting of two spring arms, is arranged to engage flattened parts of the pin under a shoulder F. The flattened part of the pin may be rectangular or oval, and is tapered off, as shown in Fig. 2. The catch G may assume any of the forms shown in Figs. 5, 6, and 7. Its free ends are held down by a guide, Fig. 1.

Title: Improvements in Free Wheel Motor and other Bicycles and Tricycles
Inventor: LARKIN JAMES
Filed: 1903-06-03
Granted: 1903-10-15
Abstract: 12,545. Larkin, J., and Larkin, T. June 3. Cranks.-In order that the pedal cranks of freewheel motor and other bicycles and tricycles may be both pressed down 'to their lowest position, in free-wheeling, the crank a, Figs. 1 and 3, is capable of making half a revolution on the spindle c relatively to the other crank, but is prevented from turning more than half round by a stop f in a groove e, Fig. 3, which strikes a flat portion on the retaining-cottar d. When the crank a is being used for driving purposes, one edge of the stop presses against the cottar, but when both the cranks are down, the other edge engages the cottar. To bring the crank back into driving position, one end of a spring is fastened to the spindle while the other is attached at h<2> to the inside of a casing g. In a modification, Figs. 6 and 7, the spindle c is divided into two parts c<1>, c<2>. The part c<1> ends in a disc i, which carries a quadrantal lug j, while a sleeve k has a diaphragm l carrying a similar projection m facing towards the right. In pedalling, the lug j bears against the lug of the sleeve, which is consequently driven round, but when both cranks are held down during freewheeling, the other edges of the lugs come into contact. The spring h keeps the cranks normally in line.

Title: An Improved Reducing Valve
Inventor: LUMLEY MAITLAND
Filed: 1904-04-18
Granted: 1904-06-02
Abstract: 8845. Lumley, M. April 18. Pressure - regulating valves; lift valves; casings; spindles; seats.- Relates to a reducing-valve for use with gas, air, &c. containers, to regulate the pressure of the gas supplied. The valve comprises a case containing a bored spindle, which is acted on by three springs, two of them acting in opposition to the third, the degree of compression of which is adjustable and determines the pressure at which the gas is delivered. Fig. 1 is a section of the valve. The gas container is connected to the valve by means of a union piece 3 through which is a passage 14 terminating in a conical valve seat 13. The valve is formed by a rubber or other plug 7 let into a spindle 6 arranged in a casing formed of two parts connected by a nut 5. The casing is provided with a screw cap 24<a>, and is connected to exit pipes 33, 34. The spindle 6 is formed with passages 9, 9<a>, the latter leading to a chamber in the upper part of the casing, the communication to the valve seat being completed by spaces between radial arms 8 which guide the valve spindle. In the closed position of the valve, the pressure of the spindle on the valve seat is relieved by means of an annular projection 31 upon which the arms 8 bear. The spindle is acted on by springs 12, 22, tending to close the valve, and by a spring 30, tending to open it. The spring 12 is confined between the arms 8 and a metal washer 11 arranged above an india - rubber washer 10<a> embracing the spindle. The spring 22 bears against a flange 16 on a nut 15 which secures a sleeved washer 17 to the spindle, and against a shoulder 23 on a screwed plug 24 closing the casing. The spring 30 abuts against a washer 20 arranged above a washer 18, and against a ring 25 provided with studs 26, which slide in slots 27 in the casing and upon which bears a nut 28, provided with a milled bead, screwing on the exterior of the casing. The tension of the spring 30 is regulated by means of the nut 28, and upon the tension of the spring 30 depends the pressure of the gas delivered through the valve. When the valve is open, gas escapes by way of the passages 9<a>, 9, 34, 33. Any gas getting past the spindle escapes through the slots 27. The nut 5 is formed with slots to allow it to pass over the studs 26.
